How do you enable the internal volume controls?

by DTFlash

I have a PC running AndroidTV x86 and the android volume controls don't do anything. Its outputting through HDMI fine and I can control the volume on the TV but I would rather use the Android remote. I saw a post about how to switch from device to android but for the life of me I can't find it again. Does anyone know where to switch it? Or a ADB command to switch what controls the volume.
